Yania Rivera-Ortiz, 29, was arraigned today before District Judge Elizabeth Romig-Gainer in Easton on charges of simple assault and harassment in the alleged March 30 assault.

Rivera-Ortiz ran about 4:30 p.m. from a multipurpose room in the Easton prison and punched fellow inmate Lillian Santiago in the head, which was witnessed by a corrections officer, records say. Santiago suffered a bruised chin, cut to her neck and a cut to a nostril, records say.

Santiago, 51, was in prison March 19 until April 18 for driving under suspension, records say.

Romig-Gainer sent Rivera-Ortiz back to the prison in lieu of $15,000 bail. Rivera-Ortiz faces formal arraignment May 2 in Northampton County Court on a simple assault charge in the alleged assault of her boyfriend, Luis Resto-Martinez, with a 10-inch kitchen knife following an argument Dec. 16 in Bethlehem.
